Kadeer was jailed from 1999 to 2005 for demanding the rights of Muslim Uighurs be recognized before going into self-imposed exile in the United States in 2005. At a press conference in Tokyo on Friday, Kadeer said she would continue a campaign calling for a boycott of the 2008 Beijing Olympics.
She criticized the Chinese government's policy of assimilating Uighur people, saying that unmarried Uighur women between the ages of 16 and 25 have been forcibly "transferred" to coastal cities as cheap workers.
According to Kadeer, only the Chinese language is allowed to be used for classes from primary school to university. The Uighur language is not used.
In May, the Chinese government also banned Uighur people from traveling to foreign countries.
Uighur people who fled from the autonomous region because of political oppression were jailed after being extradited to China by neighboring Central Asian countries, which have improved their ties with China through the Shanghai Cooperation Organization, she said.
Kadeer also said the Chinese government would further abuse human rights by using the excuse of having to host a peaceful Olympics. As such, Kadeer said she would call on international human rights organizations to boycott the Summer Games.
A native of the autonomous region, Kadeer, 60, was a member of the Chinese Communist Party. She was put behind bars for more than five years for championing human rights.
Kadeer fled to the United States in March 2005, where she now campaigns to shed light on human rights abuses in China, including testifying before the U.S. Congress.
